Shipley caught 11 passes for 147 yards and a score while also scoring on a 74-yard punt return Saturday in a 38-14 win over Colorado. Shipley now ranks seventh in the nation in receiving yards per game (116.6), second in receptions per game (9.4) and fourth in punt-return average (18.9).

That kind of production makes Shipley the new No. 1 receiver in the Rivals.com College Football Power Rankings, which measure the nation's top performers at each position. Shipley replaces Gilyard, whose team was idle last week.

"Jordan Shipley is amazing," Texas coach Mack Brown said. "What he's been able to do in the first five games seems to still not be as nationally recognized as I think it should be. He's done an amazing job."

Shipley has caught at least 10 passes in three consecutive games and heads into Saturday's showdown against Oklahoma with 47 receptions for 583 yards and three touchdowns. He also has scored on a punt return in two of his past three games.

"The things he does, it's amazing to see him do," Texas wide receiver Dan Buckner said.

Shipley wasn't the only Big 12 player to move to the top of the power rankings.

Nebraska tackle Ndamukong Suh took over the No. 1 spot in the defensive line rankings. Suh made six tackles, recorded a sack, forced a fumble and picked off a pass Thursday in the Huskers' 27-12 victory over Missouri.

Suh moved ahead of TCU end Jerry Hughes, who had one tackle in a 20-17 triumph over Air Force.

In the only other change atop the power rankings, Houston's Dana Holgorsen replaces Auburn's Gus Malzahn as the top offensive coordinator. Houston, which gained 490 yards Saturday in a 31-24 victory over Mississippi State, leads the nation in total offense (569.2 yards per game) and passing offense (443.6). Auburn fell 44-23 to Arkansas last week for its first loss of the season.

The power rankings are released each Tuesday during the regular season. The ranking of a player and coach can fluctuate each week during the season depending on how he fared the previous week. The power rankings measure overall career performances as well as their most recent results.
